System, Method, and Computer Program Product for Linking Accounts Across Systems

ABSTRACT

Provided are computer-implemented methods for linking accounts across systems which may include receiving an authorization request message including transaction data associated with a payment transaction and a primary account number (PAN); identifying a token corresponding to the PAN; transmitting a request message comprising at least a portion of the transaction data associated with the payment transaction and the token to at least one employer system, wherein the at least one employer system is associated with at least one employer institution; and receiving, from the at least one employer system, at least one response message comprising transaction adjustment data associated with an adjustment to the payment transaction. Methods may also include adjusting at least one parameter of the payment transaction based at least partially on the transaction adjustment data. Systems and computer program products are also provided.

BACKGROUND 1. Technical Field

This disclosure relates generally to linking accounts across systemsand, in some non-limiting embodiments or aspects, to systems, methods,and computer program products for linking accounts across systemsinvolved in payment transaction processing.

2. Technical Considerations

Individuals may make purchases that include adjusting the value of apayment transaction generated during the purchase. For example, anindividual may be involved in (e.g., may initiate) a payment transactionthat also involves a merchant such as, for example, an office supplystore, a pharmacy, and/or the like. To initiate the payment transaction,the individual may provide a payment device (e.g., a credit card, adebit card, and/or the like that corresponds to a payment account) to asystem associated with the merchant (e.g., a point-of-sale system) or anindividual operating the system. The system may then generate anauthorization request message based on the payment transaction andtransmit the authorization request message to one or more other systems(e.g., a transaction service provider system) to complete the paymenttransaction.

In some examples, the individual initiating the purchase may alsoprovide a secondary device (e.g., a benefits card, an employeridentification card, and/or the like) during purchase to reduce theamount due for the payment transaction. For example, the individual mayprovide the secondary device to indicate to an individual operating themerchant system that the amount due for the payment transaction shouldbe reduced. The individual associated with the merchant may then provideinput to the system to cause the system to reduce the amount due for thepayment transaction.

However, these systems may be inefficient with individuals operatingmerchant systems having to provide input to the system associated withthe merchant based on receiving the secondary device. For example, thesystem associated with the merchant may generate additional messages andtransmit the additional message (e.g., to an employer system) to verifythat the amount due for the payment transaction should be reduced. This,in turn, may increase the amount of network traffic consumed to completethe payment transaction and/or processing time involved with the one ormore other systems. Further, by virtue of human error, individualsinitiating the above-noted payment transactions may have to wait anincreased amount of time if individuals providing the input to thesystem associated with the merchant provide incorrect and/or inaccurateinput to the system and/or while the individual providing the inputverifies the identity of the individual providing the secondary device(e.g., by comparing the secondary device to another device identifyingthe individual).

Also, as used herein, theterms “has,” “have,” “having,” or the like are intended to be open-endedterms. Further, the phrase “based on” is intended to mean “based atleast partially on” unless explicitly stated otherwise.

As used herein, the terms “communication” and “communicate” may refer tothe reception, receipt, transmission, transfer, provision, and/or thelike of information (e.g., data, signals, messages, instructions,commands, and/or the like). For one unit (e.g., a device, a system, acomponent of a device or system, combinations thereof, and/or the like)to be in communication with another unit means that the one unit is ableto directly or indirectly receive information from and/or send (e.g.,transmit) information to the other unit. This may refer to a direct orindirect connection that is wired and/or wireless in nature.Additionally, two units may be in communication with each other eventhough the information transmitted may be modified, processed, relayed,and/or routed between the first and second unit. For example, a firstunit may be in communication with a second unit even though the firstunit passively receives information and does not actively transmitinformation to the second unit. As another example, a first unit may bein communication with a second unit if at least one intermediary unit(e.g., a third unit located between the first unit and the second unit)processes information received from the first unit and transmits theprocessed information to the second unit. In some non-limitingembodiments or aspects, a message may refer to a network packet (e.g., adata packet and/or the like) that includes data.

As used herein, the terms “issuer,” “issuer institution,” “issuer bank,”or “payment device issuer,” may refer to one or more entities thatprovide accounts to individuals (e.g., users, customers, and/or thelike) for conducting payment transactions, such as credit paymenttransactions and/or debit payment transactions. For example, an issuerinstitution may provide an account identifier, such as a primary accountnumber (PAN), to a customer that uniquely identifies one or moreaccounts associated with that customer. In some non-limiting embodimentsor aspects, an issuer may be associated with a bank identificationnumber (BIN) that uniquely identifies the issuer institution. As usedherein “issuer system” may refer to one or more computer systemsoperated by or on behalf of an issuer, such as a server executing one ormore software applications.

Referring now to FIG. 3, FIG. 3 is a flowchart of a non-limitingembodiment or aspect of a process 300 for linking accounts acrosssystems. In some non-limiting embodiments or aspects, one or more of thefunctions described with respect to process 300 may be performed (e.g.,completely, partially, etc.) by transaction service provider system 110.In some non-limiting embodiments or aspects, one or more of the steps ofprocess 300 may be performed (e.g., completely, partially, and/or thelike) by another device or a group of devices separate from and/orincluding transaction service provider system 110, such as user device102, merchant system 104, payment gateway system 106, acquirer system108, issuer system 112, and/or employer system 114.

As shown in FIG. 3, at step 302, process 300 may include receiving anauthorization request message including transaction data associated witha payment transaction and a primary account number (PAN). For example,transaction service provider system 110 may receive an authorizationrequest message including transaction data associated with a paymenttransaction and a PAN. In such an example, transaction service providersystem 110 may receive the authorization request message including thetransaction data associated with a payment transaction and the PAN frommerchant system 104. In some non-limiting embodiments or aspects,merchant system 104 may transmit the authorization request totransaction service provider system 110 based on user device 102initiating the payment transaction at merchant system 104. In somenon-limiting embodiments or aspects, the payment transaction may involvea user associated with user device 102 and a merchant associated withmerchant system 104.

In some non-limiting embodiments or aspects, transaction serviceprovider system 110 may determine at least one identifier for at leastone item (e.g., a good and/or a service) involved in the paymenttransaction. For example, transaction service provider system 110 maydetermine the at least one identifier for the at least one item involvedin the payment transaction based on the transaction data associated withthe payment transaction. In another example, transaction serviceprovider system 110 may determine the at least one identifier for the atleast one item involved in the payment transaction based on item dataassociated with the at least one item. In such an example, the item dataassociated with the at least one item may be included in theauthorization request message.

As shown in FIG. 3, at step 304, process 300 may include identifying atoken corresponding to the PAN. For example, transaction serviceprovider system 110 may identify a token corresponding to the PAN. Insome non-limiting embodiments or aspects, transaction service providersystem 110 may identify the token corresponding to the PAN based on(e.g., in response to) receiving the authorization request message. Forexample, transaction service provider system 110 may identify the tokencorresponding to the PAN based on (e.g., in response to) receiving theauthorization request message from merchant system 104. In such anexample, transaction service provider system 110 may identify the tokencorresponding to the PAN based on the data included in the authorizationrequest message. In some non-limiting embodiments or aspects,transaction service provider system 110 may identify the tokencorresponding to the PAN based on comparing the PAN to data included ina database. For example, transaction service provider system 110 mayidentify the token corresponding to the PAN based on comparing the PANto one or more PANs stored in association with (e.g., in correspondencewith) one or more tokens in the database. In such an example,transaction service provider system 110 may identify the tokencorresponding to the PAN based on comparing the PAN to the one or morePANs stored in association with the one or more tokens in the databaseand transaction service provider system 110 may select the tokencorresponding to the PAN in the database that matches the PAN of theauthorization request message.

In some non-limiting embodiments or aspects, transaction serviceprovider system 110 may maintain the database including the one or morePANs stored in association with the one or more tokens (referred toherein as the PAN-Token database). For example, transaction serviceprovider system 110 may maintain the PAN-Token database based onreceiving data associated with one or more PAN-Token associations fromone or more employer systems 114. In such an example, the one or moreemployer systems 114 may generate and/or transmit the data associatedwith the one or more PAN-Token associations based on receivingregistration data associated with a plurality of employees. In somenon-limiting embodiments or aspects, employer system 114 may receive theregistration data from one or more user devices 102 associated with theone or more employees. For example, employer system 114 may receive theregistration data from one or more user devices 102 associated with theone or more employees, the registration data including one or more PANscorresponding to the respective employee of the one or more employees.In some non-limiting embodiments or aspects, employer system 114 maygenerate a plurality of tokens. For example, employer system 114 maygenerate a plurality of tokens, where each token corresponds to one ormore PANs of the one or more employees. In some non-limiting embodimentsor aspects, employer system 114 may transmit data associated with theone or more PAN-Token associations to transaction service providersystem 110 based on employer system 114 generating the plurality oftokens.

As shown in FIG. 3, at step 306, process 300 may include transmitting arequest message including at least a portion of the transaction dataassociated with the payment transaction and the token. For example,transaction service provider system 110 may transmit a request messageincluding at least a portion of the transaction data associated with thepayment transaction and the token. In such an example, transactionservice provider system 110 may transmit the request message includingat least a portion of the transaction data associated with the paymenttransaction and the token to one or more employer systems 114. In somenon-limiting embodiments or aspects, transaction service provider system110 may transmit the request message based on identifying the tokencorresponding to the PAN. For example, transaction service providersystem 110 may transmit the request message based on identifying thetoken corresponding to the PAN. In such an example, transaction serviceprovider system 110 may transmit the request message based onidentifying the token corresponding to the PAN, where transactionservice provider system 110 determines that the token corresponding tothe PAN is associated with the employer system 114. Additionally oralternatively, transaction service provider system 110 may transmit therequest message based on identifying the token corresponding to the PANto multiple employer systems 114 and transaction service provider system110 may forego determining that the token is associated with the one ormore employer systems 114.

For example, user device 402 may transmita PAN to initiate a payment transaction involving one or more items tomerchant system 404 at a POS terminal associated with merchant system404. In such an example, the POS terminal may receive as input at leastone identifier for at least one item involved in the payment transaction(e.g., via scanning a barcode affixed to the at least one item).

As shown by reference number 425 in FIG. 4A, merchant system 404 maygenerate an authorization request message for the payment transaction.For example, merchant system 404 may generate an authorization requestmessage for the payment transaction based on receiving the PAN from userdevice 402. The authorization request message may include transactiondata associated with a payment transaction, the transaction dataincluding data associated with one or more parameters (e.g., a valueassociated with one or more items involved in the payment transaction, atime at which the payment transaction is initiated, and/or the like) ofthe payment transaction. Additionally or alternatively, theauthorization request message may include the PAN transmitted by userdevice 402 to merchant system 404.

As shown by reference number 430 in FIG. 4B, merchant system 404 maytransmit the authorization request message to transaction serviceprovider system 410. As shown by reference number 435 in FIG. 4B,transaction service provider system 410 may determine a tokencorresponding to the PAN. For example, transaction service providersystem 410 may determine the token corresponding to the PAN based ontransaction service provider system 410 comparing the PAN to one or morePANs included in the PAN-Token database. In such an example, transactionservice provider system 410 may select the token corresponding to thePAN included in the PAN-Token database that matches the PAN included inthe authorization request message. In some non-limiting embodiments oraspects, the PAN-Token database may be associated with a token serviceand/or a network credential linked employee benefit system. In somenon-limiting embodiments or aspects, the PAN-Token database may beconfigured to communicate with employer system 414.

For example,employer system 414 may determine transaction adjustment data associatedwith an adjustment to the payment transaction based on the tokenincluded in the request message.

As shown by reference number 455 in FIG. 4D, employer system 414 maytransmit a response message including the transaction adjustment data totransaction service provider system 410. The transaction adjustment datamay include an indication to adjust the transaction (e.g., a “YES” or“NO”) in accordance with one or more rules (e.g., one or more rulespre-established with the transaction service provider system 410).Additionally or alternatively, the transaction adjustment data mayinclude an adjustment to the payment transaction (e.g., instructions toreduce the transaction value by a percent, an updated transaction valueadjusted by the employer system 414, and/or the like). In somenon-limiting embodiments or aspects, the transaction adjustment data mayinclude a plurality of adjustments. For example, the transactionadjustment data may be associated with a plurality of adjustments to thepayment transaction. In some non-limiting embodiments or aspects, theplurality of adjustments may be tiered (e.g., may be ordered in asequence in which they should be used to adjust the payment transactionand/or the like). For example, the plurality of adjustments may betiered and transaction service provider system 410 may adjust thepayment transaction based on the tiered plurality of adjustments.

As shown by reference number 460 in FIG. 4E, transaction serviceprovider system 410 may adjust at least one parameter of the paymenttransaction. For example, transaction service provider system 410 mayadjust at least one parameter of the payment transaction (e.g., thetransaction value of the payment transaction) based on the transactionadjustment data associated with the adjustment to the paymenttransaction included in the response message (e.g., by reducing thetransaction value by 10% from 15 USD to 13.50 USD). In some non-limitingembodiments or aspects, transaction service provider system 410 may thentransmit the authorization request message after adjusting the paymenttransaction to one or more systems to process the payment transaction.For example, transaction service provider system 410 may transmit theauthorization request message after adjusting the payment transaction toan issuer system associated with the PAN. The issuer system may thentransmit an authorization response message including an indication ofwhether the payment transaction is approved or not approved (e.g.,declined). In some non-limiting embodiments or aspects, the transactionservice provider system 410 may transmit the authorization responsemessage to merchant system 404 to cause merchant system 404 to output adisplay indicating whether the payment transaction is approved or notapproved.
